CONTENTS

Safety instructions—Personal safety.

Special caution—Machine or component damage.

Read the entire manual before starting any

service work.

Ensure that ventilation (extraction) is adequate

if the engine is run indoors.

It is essential that the machine is properly cared for to

ensure satisfactory operation. Keep the machine clean to

facilitate quick and timely detection of any leakage, loose

bolts and loose connections.

TAKE CARE OF THE ENVIRONMENT

Do not leave behind any oil, fuel or other substances that

are detrimental to the environment.

This manual contains instructions for periodic activities

that should normally be performed by the operator.

For the diesel engine, the engine manufacturer’s

instructions—found in the engine manual—also

apply. This manual is included in the product

binder.

LUBRICANTS, SYMBOLS

Other fuel and lubricants are required for operation in extremely high or extremely low

ambient temperature. See the “Special instructions” chapter, or consult Dynapac.

Always use high-quality lubricants in the recommended amounts. Too much grease or oil can

cause overheating and subsequent increased wear.

MAINTENANCE MEASURES

The periodic measures should be performed primarily

after the specified hours of operation. Use the daily,

weekly, etc. time periods only where this is not possible.

Remove all dirt before filling, when checking

oils and fuel, and when lubricating with oil or

grease.

The engine manual specifies additional ser-

vice/maintenance instructions which relate to

the diesel engine.

CAUTION

Items in Measure See page Comments
